Well - I took advantage of the rainy afternoon and set up an entry point towards the “trusted network of experts”. It’s all on the WPMU instance - but I have to say for multi-site purposes Wordpress MU is crappy. Though there are WPMU functions they are limited towards on “site” approach. The usage of foreign URI like http://discovering-the-starfish.de needs some handcrafting on the MySQL DB - explained here in German: “Domain-Hosting mit MU Wordpress”. And then listing the blogs with the “get_last_updated”-function is again limited to the site UID of the main blog.

Therefore I had to build me a WPMU plugin with some extended functionality -

• get_last_updated_ext() - list all blogs from all sites
• show_list_of_blogs() - some handy presentation of the list
• get_latest_posts() - list latest postings from all sites doing a UNION-query over all WP_n_Posts-Tables (not very lean - but what the heck!)
• show_latest_posts() - some handy presentation

Then I set up some CD-compatible template - well … I don’t like the templating logic of WP - somehow I think this is also very much draining on the ressources. While the backend usability and the specific blogging functions are very neat, everything else is not yet at all a content-management system!

Before I forgot - for everyone digging into the code of Wordpress - this link was very helpful for me: http://phpxref.wordpress-it.it/nav.html?_functions/index.html
